<p>A speed reducing drive system (1) for reducing the speed of rotation of a drive motor (5), picking up the reduced speed and driving the movable portion of a video camera, a video tape recorder integrally formed with a camera or the like at the reduced speed. The drive system comprises: a small-sized or flat-shaped drive motor (5) held on a case (2, 3, 4); a worm gear (6) rotatably supported on said case; first rotation transmitting means (11) for transmitting the turning force of the drive motor (5) to the worm gear (6); and second rotation transmitting means (14, 15, 16) for transmitting the turning force of the worm gear to an output shaft (7) provided with a rotatable coupling portion coupled to the movable portion. The rotation of the drive motor (5) is transmitted to the worm gear (6) through the first rotation transmitting means, and the rotation of worm gear (6) is transmitted to the output shaft (7) at a reduced speed through the second rotation transmitting means (14, 15, 16).</p> |
